I come up with 21 ohms parallel 24 ohms series. Would this damage the MC250? I run it stereo one side not bridged. I know a 2x12 is easier but I'm curious as to how Jerry wired the 3 speaker cab. I checked past threads and couldn't find it.

After some thought if I have 2 wired to 4 ohm and add the 3rd that gives me 2+ ohms. The mc2300 had a 2 ohm tap i believe. I can put 2 in series for 16ohm + the 3rd would give me 5+ ohms. So the question is which would be better considering the mc250 does not have any tap less than 4 ohm. Neither? Stick with a 2 twelve cab? I don't want to damage the mc250

Found the thread and yes it was thrown around that they were running 2+ ohms on the 4 ohm tap but also Glenn from Hard Truckers mentioned Parish would often have a speaker back stage so they could monitor JG so the load would be even (4 speakers) in that instance. My question if anyone knows can you damge a MC this way?
